First, you need to make sure that your parser class also uses the following, additional namespaces:

• Sdl.FileTypeSupport.Framework.IntegrationApi
• Sdl.Core.Settings
• Sdl.FileTypeSupport.Framework.Core.Settings

Then your parser class needs to implement the ISettingsAware interface, which makes it 'aware' of the plug-in settings and provides the method that allows it to initialize the settings.

In the next step, add the following boolean property to your parser class:

public bool LockPrdCodes
{
    get;
    set;
}

Then, use the InitializeSettings method of the interface to initialize the plug-in setting. Within this method, we call on the UserSettings class and apply the PopulateFromSettingsBundle method to retrieve the current plug-in configuration and then set the LockPrdCodes of the main verifier component accordingly.

public void InitializeSettings(Sdl.Core.Settings.ISettingsBundle settingsBundle, string configurationId)
{
    UserSettings _userSettings = new UserSettings();
    _userSettings.PopulateFromSettingsBundle(settingsBundle, configurationId);
    LockPrdCodes = _userSettings.LockPrdCodes;
}

Modify the ProcessLine() helper function so that it triggers WriteLockedContent() only if the current line starts with the Prd-Code string and if LockPrdCodes equals True.

// determines whether a given line is
// translatable or not
// if not, a structure tag is output
// otherwise, the translatable text is exposed
private void ProcessLine(string sLine)
{
    if (sLine.StartsWith("[") && sLine.EndsWith("]"))
    {
        WriteStructureTag(sLine);
        WriteContext(sLine);
    }
    else if (sLine.StartsWith("Prd-Code") && LockPrdCodes==true)
    {
        WriteLockedContent(sLine);

    } 
    else
    {
        WriteText(ProcessFormatting(sLine));
    }
}
